The northern summer Milky Way setting over the mountains of Waterton Lakes National Park, Alberta, Canada, with the Space Station rising at right, then fading into sunset, in a trail from the series of long exposures. This is from the Bison Compound viewpoint looking south and southwest, on September 21 2019, in frames taken as part of a time-lapse. The trail fades to deep red as the ISS travels into the Earth's shadow as it rose here and experienced sunset at their altitude.
